In my forthcoming book Creative Historical Thinking (Routledge), I describe many ways in which people have different structural views of time: timelines that go up and down, this way and that; mental images of the week, month, or year, that organize information in different way.

This Dutch Calendar has the days running from top to bottom first, and then from left to right, rather than the traditional American calendar which has the days running from left to right and from top to bottom.  What a fascinating way to re-envision time!  Do you, dear reader, structure your mental month this way?

As I posted this first image, I found another Dutch calendar of the same kind of vertical/ horizational arrangement.  Is this a Dutch thing?  Does it exist elsewhere too?
